Python(common for automation)
PHP(legacy web system)
Node.js(modern application)

Sample code suggestion(Python example):

import requests

data_list = ["https://link1.com", "https://link2.com"]

for i, data in enumerate(data_list):

r = requests.get(f"https://api.qrserver.com/v1/create-qr-code/?data={data}")

with open(f"qr_code_{i}.png", "wb") as f:

f.write(r.content)

Step 3: Save the results as an image or PDF file.

The results will be saved as image files (PNG, JPG...).
Can be combined into a ZIP file or inserted into PDF using a supporting library (like reportlab, Pillow or PyPDF2 in Python).
